Vertical Motion Models--Again

Since the guest teacher wasn't able to remember how to use the quadratic equation, I took a step backwards and worked with students on how this actually works. First, we looked at a series of equations and determined whether the parabola showed a maximum or minimum, opened up or down, and named the y intercept. Next, we practiced finding the determinant, and used that to determine the number of x intercepts the graph would show. Using the handheld computers, students were able to verify their predictions. The class ended with me reminding students of what the quadratic equation looked like, and how to work through it. The key is understanding the +/- sign, and knowing that you can end up with 0, 1 or two solutions to a particular problem.
